* [BPF] Make rust allocation builtins unavailable for BPF target - the calls to rust alloc/dealloc routines need to be preserved and not replaced by compiler generated builtin inlined code
* [SOL][BPF] Adjust BPF tests * [SOL][BPF] Improve reporting of stack size is too large - issue only one warning for each function - report the function location if debug information is available

* [SOL] Make lld thread-safe with llvm when used in-process Every time Solang tries to link a web-assembly file in-process, the linker re-inits llvm which is not thread-safe with the rest of solang. Signed-off-by: Sean Young <[email protected]> * [SOL][BPF] Enable the _ExtInt extension on the BPF Target for Solana Signed-off-by: Sean Young <[email protected]>
Solana extends BPF so that structs type information is not fully supported in BTF. This leads to ICE crashes and some unsupported relocations being emitted in binary files that linker errors on. For, now the debug information is simply disabled when compiling for Solana to avoid the errors in Debug builds.
Signed-off-by: Lucas Steuernagel <[email protected]>
BTF/CO-RE has been disabled for Solana since: #37 This patch updates related code (and all applicable unit tests) from roughly a year of bitrot. This is in preparation for its possible use in the Move project. Additionally, a few other 14.0.2022-03-02 -> 15.0-2022-08-09 BPF patches were reflected in the SBF back-end (e.g., bugfixes).
EM_SBF files are only accepted by new ELF parser of the RBPF.
Because of a bug in BPF backend ABS64 relocations are incorrectly generated as 64_64 relocations in BPF object files. This temporary works around this for relocations in .debug section to generate debug information addresses correctly.

This change rust-lang@ab4fc87 breaks compilation of compiler-rt library for BPF and SBF targets. For now disabling it.
